PRODUCT DESCRIPTION

The outside CO2 transmitter device uses a highly

accurate and reliable non-dispersive infrared

(NDIR) sensor in an vented, weatherproof

enclosure to monitor outside CO2, levels. The

sensor uses dual wavelength optics and LTA (long

term adjustment) signal processing technology to

deliver industry leading long-term accuracy and

reliability.

Standard features include a field selectable output

signal of either 4-20 mA, 0-5 Vdc or 0-10 Vdc

for the highest versatility, programmable CO2

measurement span, a backlit alpha-numeric LCD

and easy menu operation for configuration.

Optional features include a resistive temperature

sensor output and a control relay with

programmable setpoint,hysteresis and time delay.
